BACKGROUND Surgical site infection (SSI) following gastric surgery has not been well documented. OBJECTIVE To describe and assess factors associated with SSI following gastric surgery in Japan using a Japanese national database for healthcare-associated infections. DESIGN A retrospective nationwide surveillance-based study. SETTING Japanese healthcare facilities. METHODS Data on gastric surgeries performed between 2012 and 2014 were extracted from the Japan Nosocomial Infections Surveillance. Gastric surgery was divided into 3 types of procedures: total gastrectomy (GAST-T), distal gastrectomy (GAST-D), and other types of gastric surgery (GAST-O). The incidence of and factors associated with SSI following gastric surgery were assessed by the 3 types of procedures. RESULTS The cumulative incidence of SSI following gastric surgery was 8.8% (3,156/36,052). The incidence of SSI following GAST-T (12.4%) was significantly higher than that following GAST-D (7.01%) or GAST-O (7.84%). Besides the 4 conventional risk factors for predicting SSI, additional risk factors were identified. Male sex was significantly associated with SSI following all types of gastric surgery, but the effect of the association was substantially different (adjusted odds ratio, 1.52, 1.47, and 1.28 for GAST-T, GAST-D, and GAST-O, respectively). The effect of an emergency operation was similar. Age was also identified as a risk factor, but the most suitable modification of age as a variable differed. CONCLUSIONS The incidence and factors associated with SSI following 3 types of gastric surgery differed. To accurately compare hospital performance in SSI prevention following gastric surgery, dividing surgical procedures in the surveillance system into 3 types should be considered.
